The "Crowded Number" Problem
In Springer paper formatting (especially LNCS), a common visual issue occurs when the section number (e.g., "2.1") sits too close to the section title (e.g., "Methodology"). This often happens if you have double-digit sections (like "10.1") where the longer number crashes into the text.
PaperFormat.net provides a specific control called "Number Margin Right (mm)". This setting defines the exact gap between the number and the text, ensuring your headings look clean and professional regardless of how long the section number is.
Step-by-Step: Adjusting the Gap
Step 1: Access the Style Tab
- Navigate to the "Style" tab in the top navigation bar.
- This tab controls the global layout rules for your document.
Step 2: Locate Heading Spacing Controls
- Scroll down to the section labeled "HEADING SPACING" (usually below the "1st Page Top" settings).
- Look for the specific field: "Number Margin Right (mm)".
Step 3: Adjust the Value
- The Default: The standard value is often small (e.g., 3 mm).
- The Fix: If your headers look crowded, increase this number.
- Example: Changing it to 5 mm pushes the text further to the right.
- Visual Confirmation:
- In the first image, the value is 3 mm, and the arrow shows a standard gap.
- In the second image, the value is increased to 5 mm. Notice how the gap between the number "2" and the word "LITERATURE" has noticeably widened.
When Should You Use This?
- Double-Digit Sections: If you have a section "12. Conclusion", the "12." is wider than "1.". You need more margin to prevent the title from looking glued to the number.
- Visual Balance: Some authors prefer a wider, more airy look for their headings to make the document easier to scan.
- Template Compliance: If a specific conference editor points out that your headings are "misaligned" or "too tight," this is the exact setting to fix it.
